CARF'ENTERS GAGE.

SPECIFICATION forming part of Letters Patent No. 273,440, dated March 6,1883.

Application filed June 1'2, 1882. (No model.)

.To all whom it may concern Be it known that I, WILBUR F. BERRY, ofChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Carpenters7 Gages, of which thefollowing, in connectionwith the accompanying drawings, is aspecification.

In the drawings, Figure l is a side view of a carpenters gage embodyingmy invention. Fig. 2 is a verticalcentral longitudinal section thereof'.FigfS is a section in the planeet' the line m ac, viewed in thedirection indicated by the arrow there shown. Fig. 4 is a section in theplane of the lineyy, viewedin theopposite direction; and Fig. 5 is abottom view ot' the guide-block.

Like letters of reference indicate like parts.

A is the stock of the gage. This stock consists of a rod or cylindricalpart, which is from six to. eight inches in length and about onehalf ofan inch in diameter. y I

Bis the cutting-gage, which consists of a sharp-edged disk having acentral opening, a. A female screw, b, is made in the front end of thestock', and C is a screw passing through the opening a and entering thescrew-hole b. By this means the'gage or disk B is held to the front endof the stock and permitted to rotate, but prevented from wabbling.

D is a sharp-pointed screw, passing through the stock and through thescrew C, thus preventing the latter from becoming loose, and at the sametime serving as a gage-point, as will hereinafter more fully appear.

E is asliding bar, having on its rear end the point c. y The bar E hasbeveled sides, and is located in a dovetail groove, d,in the stock A, asindicated in Figs. 3 and 4.

e is a depending flan ge or finger-piece on the rear end of the slide E.The rear part or end ofthe stock is iiattened, as shown atf; and j" is ahole in that part ofthe stock.

F is a guide-block, having a central opening to permit it to be slippedupon the stock and over the slideE. This slide does not wholly enter thegroove d-that is, the lower edge or side of the slide projects somewhatfrom the groove, as'shown, so that it will be in contact with the blockor guide F.

G is a set-screw entering the block F, and adapted for contact at itslower end with the stock, as indicated in Fig. 2. By turning the screwdown until it meets` the stockvthe block F will he retained or firmlyclamped upon the stock, and the slide E will also .be held in anyposition in which it may be set. y The block or guide F is adjustable onthe stock,and may be set at a greater or less distance from the forwardend thereof, and when the screw G is loosened the slide E may also beadjusted.

Fl isa shoulder on the forward face of the block F, and H and H' areinclined shoulders on the rear face of the said block. The shoulders H Hare inclined in such a direction as to facilitate marking for amiter-cut, and the shoulders H H as inclined to correspond to an Octagonruiter. v

To use this tool, I proceed as follows: For example, in hanging a door Iset the block F in such a position that when the tool is applied to therear edge of the door the shoulder F' will slide on that edge, and thepart below the shoulder will slide along the side of the door, and sothat the gage B will cut the rear edge of the door along the line whichthe longitudinal edge of the hinge will occupy. I then change theposition ofthe ltool and of the block F on the stock so that the gage Bwill cut the side of the door at a distance from the rear edge equal tothe thickness of the hinge. With a chisel I then cut out the block thusmarked or located and partly cut by the gage B, which is adapted to makea cut of a depth about equal to the thickness of an ordinary doorhinge.The gage B will cut or mark nicely against or across the grain. In doingthis work the pointsD and c should be inoperativethat is, the stock ofthe tool should be so held that they will make no marks. For example,the stock may be turned in the block F until the said points occupy alateralposition or are turned away from the relative position shown indrawings. I use the points D and c as follows: For example, in markingthe top rail of a door, in order to locate the position of the tenons onthe ends of the said rail, I set the point cadistance from the point Dequal tothe thickness of the tenon required, and then set the block F sothat it will, when held against the side of the door, cause the pointsto markV out the position to be occupied by the tenen. The dattened partf of the stock is utilized as fol- IOO through the holef, and its pointwill mark the position to be occupied by the screws for securing thehinge. All the screw-holes will thus be in the same straight line, sothat the blind will be properly hung. The llattened portion fcorresponds in length to the size of the backilap hinges usually appliedto inside blinds. The tenon-mortises may be located in like manner asthe tenons are scribed. I utilize the shoulders H and H as follows: Toscribe Work for making a miter-cut,hold the tool vertically, so that oneof the shoulders H H will rest against the edge ofthe piece to be cutand the corner of the block F overlap the upper side of' the said piece.The lower edge, g, of the block will then extend' diagonally over thepiece to he cut, and it' lhispiece be scribed. along that edge the piecewill be scribed properly for a miter-cut. By applying one of theshoulders H H to the edge of a piece to be cut and proceeding in themanner already described, the piece will he scribed for an Octagonmiter-cut. By making two shoulders H H and two shoulders H El', the toolmay be set with facility for scribing the ends of both pieces which meetin a miter or Octagon miter joint, as the case may be.

The screw D may be raised, as will be perceived on reference to Fig. 2,so that the block F may be moved over its point and set very near to thegage B. A deep countersink also receives the head of this screw, so thatit will not interfere with the adjustment of the block F when the screwis raised, as just described.

I have not here attempted to state all the uses to which this tool maybe applied with advantage, as, with the description already given", itsvarious uses will be apparentto those familiar with the art.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination, in a carpenters gage, of

the stock, the adjustable gage-block F, having thereon the shoulder F',the slide E, and its point c, and the cutting-gage B, substantially asand for the purposes specied.

2. The combination, in a carpenters gage, of the stock A, having aflattened portion,f, in which is the hole f', the rotary gaging andcntting disk B, the adjustable scribing-screw D, the slide E and itspointc,-and the adjustable block F, substantially as and for thepurposes specified.
